DOOR-HINGE.

Specification of Letters Patent.

. Patented July 26, 1910.

Application filed May 18, 1910. Serial no. 562,016.

To all whom it may concern:

Be it known that I, GEORGE H. WVI-IITE, acitizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented a new and useful Door-Hinge, of which the following is aspecification.

This invention relates to builders hardware, and particularly to a novelform of hinge to be used upon doors, windows, or other swinging parts,all as will be more fully hereinafter described and claimed, andillustrated in the accompanying drawings, in which Figure 1 is a sideelevation of a conventional form of door mounted upon a pair of myimproved hinges; Fig. 2 is a transverse section on' the broken line 2-2of Fig. 1; Fig. 3 is a vertical sectional detail through one of thehinges; Fig. l. is a vertical section through one of the hinges taken atan angle of substantially 90 to the plane of Fig. 3; Fig. 5 is a detailperspective of the lap member of the hinge; Fig. 6 is a transversesection of the butt member of the hinge; Fig. 7 is a View correspondingto that of Fig. 2, showing a modification of door frame, and Fig. 8 is adetail perspective of the removable block described below.

Throughout the following description and .on the several figures of thedrawings similar parts are referredto by like reference characters.

Among the several objects of this invention are to provide hinges whichare exceedingly neat in appearance, having no projecting parts; to holdthe door in such a position that it will always be close to the stile,having at no time a crack or space between the door and stile in whichfor instance a childs fingers may be caught and injured; to prevent to alarger extent than ordinarily the warping of the door by reason of theclose engagement thereof with the stile; to insure the easy operation ofthe door on its hinges, and to prevent creaking thereof.

Referring to the drawings by reference characters, 10 indicates anyconventional type of swinging member which may be supported upon hinges,and the door frame includes a stile 11 to which the door is hung. Anysuitable number of hinges 12 may be employed, such number beingindicated as two.

Each hinge includes a butt member 13 and a lap member 1 1. Each buttmember comprises a cylindrical barrel 13 and fastening plate 13, saidparts being connected by a web 13 The barrel 13? is hollow and openended and within which a pair of trunnion blocks 15 are. slidablymounted. Each of the blocks 15 has an upwardly or downwardly projectingtrunnion or pintle 15. The blocks are held normally in their separatedposition, as indicated in Figs. 3 and 4, by any suitable means. Themeans illustrated consists of a pair of screws 16 which pass through aslot 16" ofthe barrel and into the blocks 15. The screw heads when thescrews are holding the blocks in posifinish for the hinge when assembledand also to more fully prevent any possibility of the blocks and screwsapproaching each other each to each a filler or plug 17, illustrated inFig. 8, is introduced between the screws. when the blocks are in theirproper separated position. The outer surface or edge of the-plug 17should lie also within the outer surface of the barrel 13 The base plate13 may be secured to the stile by any convenient means. As illustratedit includes a pair of ears 18 which extend above and below the barreland through which fastening bolts or screws 19 may pass into the stile.

The lap 14 includes a base plate 14 having a plurality of holes throughwhich fastening screws or bolts 20 are adapted to be passed securing thelap into the edge of the door. The lap should be made in sizes toexactly correspond to the thickness of the door, as illustrated in Figs.2 and 7, whereby no part thereof will project beyond any part of thedoor. The lap also includes a pair of bearing plates 21, havingvertically alined bearings 21' adapted to receive the pintles 15 abovedescribed, the butt barrel 13*" substantially filling the space betweensaid bearing plates 21. The adjacent surfaces of the barrel 13 andplates 21 may if desired be provided with ball grooves 22,

and in said grooves at the upper part of the hinge may be employed aseries of antifriction balls or rollers 23, not only to sustain theWeight of the door but to relieve the pintles from a large portion ofthe lateral strain which would otherwise come upon them. Theantifriction balls may not be needed at the lower portion of the hinges,but the parts should be grooved at both ends so that the hinge Will beinterchangeable end for end, it being symmetrical in all respects.

With the door frame and stile illustrated in Flg. 2 the door may swingin one direction only, but the hinges are admirably adapted for doorsintended to swing open in either of two directions, as indicated in Fig.7, in which figure the stile 11 is plane next to the edge of the door.The door and hinges are the same for either arrangement of stile.

The hinges above described may be made of any suitable materials and therelative proportions of the parts may be varied as individual tastes maydict-ate, without departing from the spirit of the invention hereinafterclaimed.

lVhile I have shown and described the butt member as connected to thestile and the lap member to the door, it is to be understood that thehinge is susceptible of the reverse arrangement, the butt beingattachable to the door and the lap to the stile.

I claim:

1. The hereindescribed hinge comprising, in combination, a butt memberincluding a hollow open ended cylindrical barrel, a pair of trunnionblocks mounted within said barrel, each of said blocks having a pintleprojecting normally beyond the end of the bareeaaea rel, a lap memberincluding a pair of parallel bearing plates between which the aforesaidbutt barrel is received and having a pair of alined bearings to receivesaid pintles, and means to secure said blocks in extended position withtheir pintles in said bearings.

2. In a door hinge of the character set forth, the combination of a lapmember having a pair of parallel spaced bearing plates having alinedbearings, a butt member comprising a hollow cylindrical barrelreceivable between said bearing plates, said barrel having alongitudinal slot intermediate of its ends, a pair of pintle blocksmovable toward and from each other within said barrel to effectengagement between the lap and butt members, and means operative throughsaid slot for controlling the position of said blocks.

3. In a door hinge of-the character set forth, the combination of a lapmember having a pair of parallel spaced bearing plates having alinedbearings, a butt member comprising a hollow cylindrical barrelreceivable between said bearing plates, said barrel having alongitudinal slot intermediate of its ends, a pair of pintle blocksmovable toward and from each other within said barrel to effectengagement between the lap and butt members, a pair of screws operativein said blocks whereby the blocks may be moved, and a plug filling theslot between said screws, substantially as set forth.

In testimony whereof I have hereunto set my hand.

GEORGE I-I; IVHITE.
